Subject: [PATCH -next] drm/amdgpu: remove set but not used variable 'amdgpu_connector'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/amdgpu/amdgpu_display.c: In function 'amdgpu_display_crtc_scaling_mode_fixup':
drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:675:27: warning:
 variable 'amdgpu_connector' set but not used [-Wunused-but-set-variable]

It never used since introduction in
commit d38ceaf99ed0 ("drm/amdgpu: add core driver (v4)")
